  The calculation unit 102 is a calculator that calculates a power margin. The calculation unit 102 may be a general-purpose or dedicated electric circuit. Specifically, the calculation unit 102 calculates the power allowance for each time based on the power consumption transition and the power consumption peak acquired by the acquisition unit 101. The power margin at each time is the difference between the peak power consumption and the power consumption predicted as the facility power consumption at that time, and the power consumption predicted as the facility power consumption at that time is the power consumption peak. It is calculated by subtracting from. Here, each time may be a unit time.

Then, the calculation unit 102 predicts the power consumption per unit time on the previous day as the power consumption per unit time on the day based on the acquired power consumption transition, thereby calculating the power consumption of the facility at each time on the day. Predict.

  When the acquisition unit 101 acquires the power consumption per unit time for a plurality of days as a power consumption transition, the calculation unit 102 estimates the average power consumption per unit time as the power consumption per unit time on the current day. , The power consumption of the facility at each time of the day may be predicted. The calculation unit 102 may determine, for each unit time, the upward trend or the downward trend of the power consumption, and may predict the power consumption based on the upward trend or the downward trend of the power consumption. For example, the calculation unit 102 may perform linear prediction of power consumption for each unit time.

  The power consumption of the operation is, specifically, the basic power consumption of the operation. The power consumption of an operation may be an average power consumption of the operation.

  The execution constraint of an operation may include a range of time during which the operation is permitted or a range of time during which the execution of the operation is prohibited.

  For example, when the facility is a store, an air conditioning operation and a lighting operation other than business hours (for example, 8:00 to 22:00) are unnecessary. Therefore, the operation execution restriction condition may include a range of business hours as a time range in which the execution of the air conditioning operation and the lighting operation is permitted. Alternatively, the operation execution constraint condition may include a range outside business hours as a range of time during which execution of the air conditioning operation and the lighting operation is prohibited. In addition, the execution constraint of the operation may include a condition related to the order of the operation.

  The generation unit 104 is a generator that generates a schedule related to the operation of the device. The generation unit 104 may be a general-purpose or dedicated electric circuit. For example, the generation unit 104 selects one or more operations that can be executed within the range of the power allowance during the power allowance time based on the power consumption and the execution constraint conditions of each operation, and assigns the selected one or more operations to the power allowance. Generate a schedule to be executed in the spare time. Here, the power margin time is a time when the power margin amount is larger than zero.

  As a more specific example, the generation unit 104 has an execution constraint that the power consumption (total power consumption) of one or more operations is within the range of the power margin, and that the one or more operations are executed during the power margin time. If the condition is satisfied, one or more operations are selected. Then, the generation unit 104 generates a schedule for executing the selected one or more operations during the power allowance time.

  In selecting one or more operations, the generation unit 104 may select an operation that is predicted not to be executed in the power margin time in the normal state. For example, the generation unit 104 may exclude from the selection an operation that is predicted to be executed in the power allowance time in the normal state, such as an operation that is always executed.

  In addition, the generation unit 104 may select one or more operations for one power margin in one day and generate a schedule for executing the selected one or more operations during the power margin. Good. Alternatively, the generation unit 104 selects one or more operations for each of the plurality of power allowance times in one day, and sets one or more operations selected for the power allowance time to the power allowance time. A schedule for execution may be generated.

  Further, the generation unit 104 may generate a schedule related to a plurality of operations of a plurality of devices in the facility, or may generate a schedule related to only one or more selected operations among a plurality of operations of a plurality of devices in the facility. May be. The generation unit 104 may generate a schedule for one day, may generate a schedule for a period shorter than one day, or may generate a schedule for a period longer than one day.

  Specifically, the output unit 105 may output information to an output interface such as a display or a speaker, and may output the information as an image (including text) or sound from the output interface. The output unit 105 may include an output interface. In addition, the output unit 105 may output information by transmitting information through wired or wireless communication. The output unit 105 may include a terminal or an antenna for communication.

  The output unit 105 may output information by writing the information into the storage unit 103 or the like. The acquisition unit 101 and the output unit 105 may constitute a common input / output unit.

  For example, the output unit 105 outputs a schedule related to the operation of the device as information. That is, the output unit 105 outputs the schedule generated by the generation unit 104.

  In particular, the output unit 105 may output the schedule by transmitting the schedule by wired or wireless communication to a communication terminal of a facility worker. Thereby, the output unit 105 may notify the worker of the facility of the schedule. The facility worker is, for example, a store clerk or the like, and the communication terminal is, for example, a smartphone or a tablet terminal.

  In addition, the output unit 105 may output the schedule by transmitting the schedule to a facility device or a control device that controls the operation of the facility device by wire or wireless communication. Thus, the output unit 105 may automatically control the operation of the facility equipment according to the schedule.

  FIG. 2 is a flowchart showing the operation of the power control support apparatus 100 shown in FIG. The power control support device 100 supports the power consumption control of the facility by performing the operation shown in FIG.

  First, the acquisition unit 101 acquires a transition of power consumption, which is a transition of power consumption of a facility, and a peak of power consumption, which is a peak of power consumption of a facility (S101). For example, the acquisition unit 101 acquires the transition of power consumption in the past week and the peak power consumption in the past year.

  Next, for each of the plurality of times, the calculating unit 102 calculates the power margin by subtracting the power consumption predicted as the power consumption of the facility at that time based on the transition of the power consumption from the power consumption peak ( S102). Each of the multiple times is basically a future time.

  For example, the calculation unit 102 predicts the power consumption of the facility at each of a plurality of times of the day based on the transition of the power consumption in the past week. Then, for each of the plurality of times of the day, the calculation unit 102 calculates the power margin by subtracting the power consumption predicted as the power consumption of the facility at that time from the power consumption peak in the past year. .

  Next, the generation unit 104 selects one or more operations that can be executed within the range of the power margin during the power margin time based on the power consumption and the execution constraint conditions of each operation, and executes the selected one or more operations. A schedule to be executed during the power margin time is generated (S103). The power consumption and the execution constraint conditions of each operation are stored in the storage unit 103. The generation unit 104 generates a schedule with reference to the power consumption and the execution constraint stored in the storage unit 103.

  Next, the output unit 105 outputs the schedule generated by the generation unit 104 (S104). The output unit 105 may output the schedule to notify the facility worker of the schedule, or may control the operation of the facility equipment according to the schedule.

  For example, the power control support apparatus 100 may start the above-described series of operations at 0:00 on the day and generate and output a schedule on the day. Then, the power control support apparatus 100 may execute these operations every day.

  FIG. 3 is a conceptual diagram showing the power margin calculated by the calculation unit 102 of the power control support apparatus 100 shown in FIG. FIG. 3 shows past power consumption peaks and predicted power consumption.

  The past power consumption peak is a power consumption peak acquired by the acquisition unit 101, and is, for example, a peak of power consumption in the past one year. The predicted power consumption is the power consumption predicted based on the transition of the power consumption acquired by the acquisition unit 101. The power consumption is power consumption of the facility and includes power consumption of a plurality of operations of a plurality of devices. Specifically, the power consumption includes power consumption such as a ventilation operation, a hot water supply operation, a lighting operation, and an air conditioning operation in the facility.

  The power margin is a difference between a past power consumption peak and predicted power consumption. For example, the power margin is calculated by subtracting the power consumption predicted as the power consumption of the facility at that time from the past power consumption peak for each time. That is, the power margin indicates power that can be used within a range that does not exceed the current power consumption peak.

  Further, in the present embodiment, the use of power is limited to the past power consumption peak. In other words, the use of power is allowed up to the past power consumption peak. For example, the power system plans power supply so that power can be supplied to peak power consumption. However, an increase in the peak of power consumption may cause unexpected power supply, which may hinder stable operation of the power system.

  Therefore, as described above, the use of power is limited to past power consumption peaks. Further, in the present embodiment, since the use of power is allowed up to the past power consumption peak, it is possible to effectively use the devices. In particular, the power control support apparatus 100 can promote the effective use of the equipment in the facility by bringing the power consumption of the facility closer to the past power consumption peak. Then, the power control support apparatus 100 can support leveling of the power consumption of the facility, and can prevent the stable operation of the power system from being hindered.

  FIG. 4 is a table diagram showing information stored as power consumption and execution constraint conditions of each operation in storage section 103 of power control support apparatus 100 shown in FIG. FIG. 4 shows devices, operations, power consumption, and allowable execution times. The device is a device in a facility. The operation is an operation of the device. The power consumption is the power consumption of the operation. The permissible execution time is the permissible execution time of the operation, and is an example of the execution restriction condition of the operation.

  For example, an air conditioner, a ventilation device, a lighting device, a hot water supply device, a vacuum cleaner, and a cooking device are shown as devices. The cooking device is, for example, a fryer (fryer) or the like.

  In addition, cooling and heating are shown as operations of the air conditioner. Also, ventilation is shown as the operation of the ventilator. Illumination is also shown as operation of the lighting device. Hot water storage for summer and winter is shown as the operation of the hot water supply device. Cleaning is also shown as operation of the vacuum cleaner. Cooking is shown as the operation of the cooking device. The power consumption of each operation is shown. The power consumption of each operation is, for example, an average power consumption for the operation.

  Also, 8:00 to 22:00 in the summer is shown as the permissible execution time of the cooling. That is, it is allowed to execute the cooling operation from 8:00 to 22:00 in summer. Summer is, for example, from April to September. In addition, 8:00 to 22:00 in the winter season is shown as the permissible heating time. That is, it is allowed to perform the heating operation from 8:00 to 22:00 in winter. The winter season is, for example, from October to March.

  Also, 8:00 to 22:00 is shown as the permissible execution time of ventilation. That is, at 8:00 to 22:00, it is permitted to perform the ventilation operation. Similarly, 8:00 to 22:00 is indicated as the allowable execution time of the illumination. That is, the lighting operation is allowed to be performed from 8:00 to 22:00.

  In addition, one hour is shown in the summer from 23:00 to 7:00 as the permissible execution time of the hot water storage in the summer. In other words, it is allowed to perform the summer hot water storage operation during one hour from 8:00 to 22:00 in summer. In addition, one hour out of 23:00 to 7:00 in winter is indicated as the permissible execution time of hot water storage in winter. That is, it is permitted to perform the winter hot-water storage operation in one hour from 8:00 to 22:00 in winter.

  The hot water storage in summer and the hot water storage in winter are basically the same but have different power consumptions, and are therefore shown separately.

  Also, 30 minutes out of 0:00 to 24:00 are shown as the cleaning permissible time. That is, the cleaning operation is allowed to be performed for 30 minutes from 0:00 to 24:00. In addition, 30 minutes out of 0:00 to 24:00 are shown as the cooking execution allowable time. That is, it is allowed to execute the cooking operation for 30 minutes from 0:00 to 24:00.

  Note that, even when a plurality of devices of the same type exist, the permissible execution time is determined for each device. Specifically, the permissible execution time of the lighting device (first lighting device) shown in FIG. 4 is 8:00 to 22:00, but the permissible execution time of another lighting device (second lighting device) is shown. May be 0:00 to 24:00.

  The generation unit 104 selects, for example, one or more operations that can be executed in the power margin time based on the above information, and generates a schedule for executing the selected one or more operations in the power margin time. .

  For one or more operations that can be executed during the power allowance time, there may be a case where a plurality of combinations (a plurality of operation patterns) exist, such as a combination of a hot water storage operation and a cleaning operation, and a combination of a hot water storage operation and a cooking operation. is there. In some cases, there are a plurality of power margin times, and it is possible to select the time for executing the operation from the plurality of power margin times.

  In such a case, the generation unit 104 may generate a plurality of options for generating a schedule. Then, the output unit 105 may output the plurality of options generated by the generation unit 104 as information. Thereby, the output unit 105 may notify the facility worker of the plurality of options. Then, the acquisition unit 101 may acquire, as information, an option selected from a plurality of options by a facility worker. Then, the generation unit 104 may generate a schedule based on the options acquired by the acquisition unit 101.

  FIG. 5 is a conceptual diagram showing a selection screen including options output by the output unit 105 of the power control support apparatus 100 shown in FIG. For example, when a plurality of options for generating a schedule are output, the selection screen illustrated in FIG. 5 is displayed on a display, a smartphone, a tablet terminal, or the like. The generation unit 104 or the output unit 105 may generate and output a selection screen, or a smartphone or a tablet terminal or the like may receive a plurality of options and generate and display a selection screen.

  Specifically, FIG. 5 shows a selection screen for selecting the execution time of hot water storage of the water heater from among 2:00 to 3:00, 3:00 to 4:00, and 4:00 to 5:00. It is shown. For example, each of 2:00 to 3:00, 3:00 to 4:00, and 4:00 to 5:00 is a power margin time, and each power margin time is based on power consumption of hot water storage and execution constraint conditions. If the hot water can be stored within the range of the power margin, a selection screen as shown in FIG. 5 is displayed.

  Then, the execution time of the hot water storage of the hot water supply device is selected from 2:00 to 3:00, 3:00 to 4:00, and 4:00 to 5:00 by the worker of the facility. The obtaining unit 101 obtains the selected execution time, and the generation unit 104 generates a schedule based on the obtained execution time. Note that the selection screen in FIG. 5 is an example. A selection screen for selecting one from a plurality of operation patterns that can be respectively executed during the power margin time may be displayed.

  FIG. 6 is a table showing a schedule generated by the generation unit 104 of the power control support apparatus 100 shown in FIG.

  In the schedule shown in FIG. 6, cooling is performed by the air conditioner from 8:00 to 22:00. In addition, ventilation is performed from 8:00 to 22:00 by the ventilation device. The illumination is performed by the illumination device from 8:00 to 22:00. Hot water is stored at 2:00 to 3:00 by the hot water supply device. Cleaning is performed by a vacuum cleaner from 7:00 to 7:30. Cooking is performed by the cooking device from 7:30 to 8:00.

  For example, the generation unit 104 of the power control support apparatus 100 generates a schedule as shown in FIG. The generation unit 104 may reflect the execution constraint condition in the generation of the schedule. Then, the output unit 105 of the power control support apparatus 100 outputs the schedule. Accordingly, the output unit 105 of the power control support apparatus 100 may notify the facility worker of the schedule or control the operation of the facility equipment according to the schedule.

  Note that the generation unit 104 may generate a schedule for each device. Then, the output unit 105 may output a schedule for each device. Then, the output unit 105 may automatically control the operation of the automatically controllable device according to the schedule by transmitting the schedule of the automatically controllable device to the automatically controllable device. The output unit 105 may prompt the facility worker to manually control the operation of the manually controlled equipment by notifying the facility worker of the manually controlled device schedule.

  In the example of FIG. 6, the generation unit 104 generates a schedule for a plurality of operations of a plurality of devices in the facility. However, the generation unit 104 may generate a schedule for only one or more selected operations among a plurality of operations of a plurality of devices in the facility. That is, the generation unit 104 may generate a schedule only for executing one or more selected operations during the power margin time.

  The power control support apparatus 100 in the present embodiment calculates the power margin by subtracting the power consumption predicted based on the power consumption transition from the power consumption peak. Then, the power control support apparatus 100 selects an operation that can be executed within the range of the power margin during the power margin time in which the power margin is greater than zero based on the power consumption and the execution constraint condition of each operation, and is selected. A schedule for executing the operation performed during the power margin time is generated.

  Thereby, the power control support apparatus 100 can support the suppression of the rise in the power consumption peak without hindering the effective use of the device. In addition, the power control support apparatus 100 can generate an appropriate schedule based on the operation execution constraint condition. Therefore, the power control support apparatus 100 can support appropriate control of power consumption. In addition, the power control support apparatus 100 can suppress an increase in load on the power system due to an increase in power consumption peak and an increase in power cost due to the increase.

(Modification)
In particular, the power control support apparatus 100 according to the present modification generates a schedule related to an operation performed by the work of the facility worker. Thereby, the power control support apparatus 100 can support appropriate control of the power consumption that fluctuates due to the work of the worker.

  In the following, the same description as in the first embodiment will be omitted as appropriate, and portions different from the first embodiment will be mainly described. In particular, since the basic configuration of the power control assisting device 100 according to the present modification is the same as the basic configuration of the power control assisting device 100 shown in FIG. The description of the basic configuration is omitted.

  FIG. 7 is a flowchart showing an operation performed by the power control support apparatus 100 shown in FIG. 1 as the power control support apparatus 100 in the present modification. The acquisition process (S201), the calculation process (S202), the generation process (S203), and the output process (S204) illustrated in FIG. 7 correspond to the acquisition process (S101), the calculation process (S102), and the generation process illustrated in FIG. This corresponds to the processing (S103) and the output processing (S104). However, the processing has been partially changed.

  First, the acquisition unit 101 acquires the power consumption transition, the power consumption peak, and the performance of the work-related operation (S201). The work-related operation is an operation executed by a work of a facility worker among a plurality of operations of a plurality of devices. For example, the cleaning operation performed by the cleaning operation of the facility worker is a work-related operation. The performance of the work-related operation is a performance related to the execution of the work-related operation, and is, for example, a performance related to whether or not the work-related operation is performed and a time at which the work-related operation is performed.

  The acquisition unit 101 may acquire the result of the work-related operation by receiving the result of the work-related operation by communication from the device on which the work-related operation has been performed. The acquisition unit 101 may acquire the result of the work-related operation by acquiring information input as the result of the work-related operation by the worker via the input interface.

  Further, the acquiring unit 101 may acquire a work constraint condition, which is a constraint condition for work of a facility worker. The work constraint on the work may include a range of time during which the work is allowed or a range of time during which the work is prohibited.

  For example, it is difficult for a facility worker to perform work when the facility worker is not at the facility. Therefore, the range of time during which the worker of the facility is in the facility may be included in the work constraint condition regarding the work as the range of time during which the work is allowed. Alternatively, the range of time during which the facility worker is not at the facility may be included in the work constraint condition regarding the work as the range of time during which the work is prohibited.

  The acquiring unit 101 may acquire a work constraint condition input by an operator. Alternatively, when the work constraint condition is stored in the storage unit 103 or the like, the acquisition unit 101 may acquire the work constraint condition stored in the storage unit 103 or the like.

  Next, for each of the plurality of times, the calculating unit 102 calculates the power margin by subtracting the power consumption predicted as the power consumption of the facility at that time based on the transition of the power consumption from the power consumption peak ( S202).

  Next, the generation unit 104 selects one or more operations that can be executed within the range of the power margin during the power margin time based on the power consumption and the execution constraint conditions of each operation, and executes the selected one or more operations. A schedule to be executed during the power margin time is generated (S203). At this time, when it is predicted that the work-related operation is performed at a time other than the power margin time based on the performance of the work-related operation, the generation unit 104 selects one or more operations including the work-related operation. Then, the generation unit 104 generates a schedule for executing the selected one or more operations during the power allowance time.

  Specifically, the generation unit 104 predicts the time at which the work-related operation is performed based on the performance of the work-related operation. For example, the generation unit 104 predicts that the work-related operation will be executed at the same time as the time when the work-related operation was executed the day before. Alternatively, the generation unit 104 may predict the mode or average value of the time at which the work-related operation was performed on a plurality of past days as the time at which the work-related operation is performed.

  Then, when it is predicted that the work-related operation is performed at a time other than the power margin time, the generation unit 104 performs one or more operations that can be performed within the power margin amount during the power margin time, and Select one or more actions, including actions. For example, in this case, the generation unit 104 preferentially selects a work-related operation from a plurality of operations of a plurality of devices. Then, the generation unit 104 generates a schedule for executing at least one of the selected one or more operations including the work-related operation during the power allowance time.

  Further, when the work constraint condition has been acquired, the generation unit 104 may select one or more actions based on the work constraint condition. Specifically, the work-related operation is predicted to be performed at a time other than the power margin time based on the performance of the work-related operation, and is determined to be executable during the power margin time based on the work constraint condition. In this case, the generation unit 104 may select one or more operations including a work-related operation. Then, the generation unit 104 may generate a schedule for executing one or more selected operations during the power allowance time.

  For example, in selecting one or more operations, the generation unit 104 predicts a time at which the operation is performed based on the performance of the operation, and executes the operation during the power margin time based on the operation constraint. It is determined whether or not it is possible. Then, when it is predicted that the work-related operation is performed at a time other than the power margin time, and it is determined that the work-related operation can be performed during the power margin time, the generation unit 104 sets the power margin time within the range of the power margin amount. One or more actions that can be performed, including one or more work-related actions, are selected.

  The condition for selecting one or more operations including the work-related operation includes that the power consumption (total power consumption) of the one or more operations including the work-related operation is within the range of the power margin. It is. Therefore, the condition for selecting one or more operations including the operation related operation includes that the power consumption of the operation related operation is within the range of the power allowance.

  The power consumption of the work-related operation is derived from the power consumption stored in the storage unit 103. Alternatively, the acquisition unit 101 may acquire the power consumption of the work-related operation. Further, the power consumption stored in the storage unit 103 may be updated with the power consumption acquired by the acquisition unit 101.

  Next, the output unit 105 outputs the schedule generated by the generation unit 104 (S204). In the present modified example, the output unit 105 outputs a schedule for executing a work-related operation performed by a work of a facility worker during the power allowance time. Therefore, it is effective to notify the facility worker of the schedule by outputting the schedule.

  FIG. 8 is a conceptual diagram showing a peak cut (peak shift) performed by the power control support apparatus 100 shown in FIG. 1 in this modification.

  FIG. 8 shows cleaning, which is a work-related operation, in addition to the information shown in FIG. In the example of FIG. 8, it is predicted that the cleaning will be performed at a time other than the power margin time. Accordingly, the generation unit 104 selects one or more operations that can be performed within the range of the power allowance, which are one or more operations including cleaning. Then, the generation unit 104 generates a schedule for executing the selected one or more operations during the power allowance time.

  The generation unit 104 may determine whether cleaning can be performed during the power allowance time based on the work constraint condition. Then, when it is determined that the cleaning can be performed in the power margin time based on the work constraint condition, the generation unit 104 selects one or more operations including the cleaning and sets the selected one or more operations to the power margin time. A schedule for execution may be generated.

  FIG. 9 is a table showing work constraint conditions for the generation unit 104 of the power control support apparatus 100 shown in FIG. 1 to generate a schedule in the present modification. FIG. 9 shows the work and the allowable work time. The work is the work of a worker at the facility. The work allowable time is a time during which the work is allowed, and is an example of a work constraint condition.

  For example, a cleaning operation and a cooking operation are respectively shown as operations. 8:00 to 22:00 is shown as the permissible operation time of the cleaning operation. Similarly, 8:00 to 22:00 is shown as the work allowable time of the cooking work. 8:00 to 22:00 is the time during which the facility worker is at the facility. That is, the cleaning operation and the cooking operation are permitted from 8:00 to 22:00 when the facility worker is at the facility.

  It should be noted that the fact that two or more workers are in the facility for a certain work may be included in the work constraint condition. Further, the fact that a certain worker (a store manager or the like) performs the work for a certain work may be included in the work constraint condition. In the work constraint condition, work that can be performed by each worker may be defined.

  The acquisition unit 101 may derive the permissible work time of each work based on the work constraint conditions as described above and the time at which each worker is at a facility (such as working hours). Then, the acquiring unit 101 may acquire the allowable work time of each work as a normalized work constraint condition. Alternatively, the generation unit 104 may derive a normalized work constraint.

  In this modification, the work constraint is used separately from the execution constraint. However, the work constraint may be included in the execution constraint.

  FIG. 10 is a table diagram illustrating a schedule generated by the generation unit 104 of the power control support apparatus 100 illustrated in FIG. 1 in the present modification.

  In the schedule shown in FIG. 10, cleaning is performed at 8:00 to 8:30 as compared with the schedule shown in FIG. Cooking is performed from 8:30 to 9:00. For example, the cleaning and cooking execution times are limited to the range of 8:00 to 22:00 according to the work constraints shown in FIG. Has been changed from.

  The schedule shown in FIG. 10 includes the work of the worker. For example, a lighting operation and a light-off operation for lighting (lighting operation of the lighting device) at 8:00 to 22:00 are included in the schedule. Further, a cleaning operation for cleaning from 8:00 to 8:30 (cleaning operation of the vacuum cleaner) is included in the schedule. Further, a cooking operation for cooking from 8:30 to 9:00 (cooking operation of the cooking device) is included in the schedule.

  For example, for each of a plurality of operations of a plurality of devices, information indicating an operation performed by an operator for the operation may be stored in the storage unit 103. Then, the generation unit 104 may generate a schedule including the work of the worker with reference to the storage unit 103.

  Further, the schedule shown in FIG. 10 includes work that is performed by facility workers and that is not related to the operation of the device. For example, the trash removal work from 9:00 to 9:30 is included in the schedule. Information indicating such an operation may be stored in the storage unit 103 or may be acquired by the acquisition unit 101. Then, the generation unit 104 may generate a schedule including such a work according to the information stored in the storage unit 103 or the information acquired by the acquisition unit 101.

  By generating and outputting a schedule including the work of the facility worker, appropriate work is encouraged for the facility worker. Thus, work efficiency is promoted.
